China Iceberg Ratio

Formula

Iceberg Ratio = Consolidated Public Sector Debt (high) / Central Government Debt (official)

• Consolidated High – IMF Article IV upper-bound estimate of total public sector leverage
• Central Official – MoF-reported on-budget central government debt (IMF GGXWDG / World Bank)
• Five-layer stack: central, local gov, LGFV, policy banks, SOE contingent

Why It Matters

China's MoF-reported central government debt (~25% GDP) dramatically understates the consolidated public sector balance sheet. The Iceberg Ratio operationalises this divergence: values above 2.0× indicate the shadow stack (LGFV + policy banks + SOE guarantees) exceeds official debt by a factor that historically precedes fiscal stress episodes in other EM economies.

Institutional Use

Used alongside IMF Article IV surveillance and BIS credit-to-GDP data by EM sovereign desks monitoring China LG bond rollover risk. Pairs with four additional composites (LGFV stress, monetization pressure, debt wall proximity, land fiscal dependence) on the Intel China debt terminal.
